This invention relates to improvements i-n antigfriction` bearings.

The primary object of this invention is .the provision of an improved adjustable bearing structure ofthe roller type', primari-ly adapted for' use' inconne'ction with the support of carY wheels upon their axles.

A' further and important object vof this invention is' the provision of' improved antifrictlion bearings for the car wheels ofl rail way. rolling stock, including novel antl-` friction means of a. simplified nature `for supporting car wheelsu lon their axles, l y y and adjusting structure C, the vouter race 22 4thereof is of ring shaped formation, -and whereby to reduce the dra t tonnage, and to eliminatel sharp iianges and wearl on curves. Other objects' and advantages of the' improved anti-friction bearing for carv wheels will be apparent during the course ofthe following detailed description. i

Figure 4 is a cross lsectional view' takenv substantially on .the line 4'-4 of Figure 1. v J Figures' 5' and 6 are details of this invention.

In the drawings, wherein for the purpose,

main portions B- of car wheel structuresarel supported by the improved anti-friction bearing and adjusting structures C.

The aXleA is of any approved type, in-lk cluding the main body 10 withthe-red-uced spindle extensions 11 and 12 at the outer 1'3 at the juncture thereof with the main body 10. t the outer ends of the externally' smooth surfaced spindles 11 re'duced screw .n threaded Shanks 14 and are respectively perspective: views 0f ends thereof, providing annular shoulders provided, for receiving attaching-means to be' subsequently described.

As the body portion B and anti-friction means C oft the car wheel structures are identical for each of the spindles 11 and 12, but one of the same will be described, the body portion- B consists of a ringl shaped casting having the outer retain-ing flange 20 thereon, and providing the open-ing 21there through which hasthe outer race 22 of the anti-friction bearing Cv driven therein with a forced fit.'` l y i Referring specifically to the anti-friction providesan' annular groove' 24 preferably midway between the inner androu'ter surfaces 25I and 26 respectively thereof, and in a plane*parallell with said surfaces. From the annular groove 24 the bearing surfaces 27V and 28 ofl sai-douter race diverge, on a taper disposed at any convenient angle as determined by the gauge of the wheels on be shrunk'upon one of the spindles 11er 12 of the aXle A, with the inside'surface 36 thereof in abutting relation withthe spindle` -sho-ulder13. This section is disposed in a .spaced cooperating relation with an outer section 39 of theinside race structure, the race section 39 being spaced from thesection 35- to provide a groove 40vannularly disposed about'the spindle which is adapted -to the axle A. At the sides of the outerfrace receive feltvmaterial or other absorbent packi ingl41. @n each side of the annular' groove or space40, the outer surfaces of the-'inner race sections 3'5 and 39 respectively provide the tapered bea-ring surfaces 44 and 45, dis; posed in a diver-'ging relation from' the passageway or space 40, and at the out-side edges of said tapered bearing surfaces 44 and 45, annularly projecting flanges 50 and 51 are ico u provided for the sections 35 and 39 respectively, adapted to cooperate with the in-'J Awardly extending flanges and 3l of the outside race 22 in enclosing the roller bearing to be subsequently described.

For Vthe purposes of adjust-ment, the'outside race section 39 of the inner race structure is adjustable along the spindle on which it is positioned, although it has a inachined snug lit upon said spindle to prevent its rotation thereabout when the car wheel is rotated about the axle.

Referring to the specific structure of each roller bearing, a plurality of the same are provided in positioned relation between the outer, and inner race structures in bearing engagement with the tapered bearing surfaces of said race structures. Each one of these roller bearingsis of the sanie conf struction, and they are preferably of the lar guide tiangel 59 atthe juncture of the' cone portions 56 and 57. From the guide flange 59 the cone portions 56 and 57 taper in converging relation `toward their peaked ends, and are flat surfaced at said ends.

The anti-friction rollers 58 are positioned so that the guide flanges 59l thereof extendik into the guide groove 24 of the outer race structure 99 and the cone portions 56 andI openings of the lugs 74 and 75 of the sections 70 and 7 1, whereby not only to clamp n the arch bars to said sections, but also to clamp said sections in a fixed relation about the spindles of the axle A.'

Nutsy 8O:L are provided for the screw threaded Shanks la `and 15 of each of the axle spindles, each of these nuts including a polygonal wrench engaging head 81 and a reduced inwardly extending sleeve port-ion 82, both the head and sleeve being provided with aninteinally screw threaded passageway 84 for threaded engagement with the Shanks 1e and 15 of the axle spindle. The outer circumference of the sleeve portion 82 of each of the nut structures is provided with an annular groove 86 therein, which is adapted to be disposed in a facing relation with the annular grooves 87 provided inwardly of the recesses 73 of the so called mock journal box sections 70 and 71;: f course, it is thus apparent that the sleeve portions 82 of the clamping nuts 8On exf 'inocl; journal sections, and the annular O'rooves 86 and 87 in fact provide an annupelar passageway for receiving" a retaining ring 89, which inay be split, and whiclris provided for connecting lthe niock'7 journal 57 rest on the tapered bearing surfaces of `box sections to the clainping nut 80 to prethe inner and outer race structures above vent any nioveinentl of the saine away frein described, and as is illustrated in Figure 1 each other. The retaining ring 89 is of the of the drawings. In this relation the end Icontractile type and is first placed in the ansurfaces oi the cone portions 56 and 57 nular groove 86 of the nut sleeve 82, and the each vroller bearing are spaced a short dis-SGC'f-ODS 70 and 71 0f the inock7 journal tance frein the enclosing flanges 30, 31, 50bOX Structure are then clainped about the and 51 of the inner and outer race structures, andthe outer circumference of the guide flanges 59 of said roller bearings are spaced from the inner circumference of the groovev 24 and also froin the outer circumference of ture is positioned, to providevspace for ad- .justineiit as the bearings and bearingrsurfaces wear. l

Referring to that part of the structure C which pertains to the retention of the adjustment of the anti-friction bearings, thev to receive the spindle ends of the axle A therein. Outwardly extending'lugs 74 and are provided at the ends of each section 7 (l and l71, flush with the outside surfaces of said sections, and which lugs are providedy .are bolted thereto, as by bolts '7 9 and 80, `which extend through the aligning end jaxle spindle and the sleeve 82 in such relaion that the projecting portions of the re aining ring 89 will enter the annular groove 87 provided by the mock journal box scctions. the spindle on which the anti-frictionl struc- To'prevent accidental rotation of the nut with respect tothe sections 70 and 71, a substantially ring shaped nut retainer 90 is provided, which preferably has a polygonal opening 91 adaptedto be slipped over the nut head 81. This retaining ring 90 has a lateral extension 92 thereonprovided with anarcuate slot 93 which is concentrically aranged with the axis of the axle when the retaining ring is in position, and so that a y clamping or set screw 9-1 may be disposed through the slot 93 and engage in one of the inock journal box sections whereby to.v clainp the nut against rotational inovenient with respect to said sections of the mock .journal box. f

Froin the foregoing description of the 'details of this invention .it .is believed' that the inanner of adjustn'ient to compensate for any Wear on the bearings or bearing surfaces will be apparent. Such take-up of the antifriction bearings consist of first releasing the nut retaining ring 90, so that the nut 8OEl may be rotated kupon the screw threaded shank of the axle spindle; the bolts 79 and 80 of the mock journal box structure of course having been loosened. Upon proper rotation of the nut 80a the same. Will then move the mock journal box sections against the outermost section 39 of the inner race structure, and slides the same longi tudinally inwardly along the spindle. This Will shift the anti-friction bearings slightly inward toward the stationary section 35, and move said anti-friction bearings into more snug litting relation With the tapered bearing surfaces of the inner and outer race structures.

Any additional improved features may be provided in connection with the improved structure herein described, such as ahigh pressure lubricating system for the anti-fricA tion bearings. It Will ol' course be apparent that the anti-friction bearings will be prevented from binding because of the fact that they are maintained in a true alignment relativel to each other by means of the guide flanges 59 thereofextending into the guide groove 24 of the outer rac-e structure 22.

Various changes in the shape, size and arrangement of parts may be made to the form of the invention herein illustrated and described, Without departing from the spirit oi' the same or the scope of the claims.

I claim: v
